1 all whom it may concern:

Be it known that I, l/VILLIAM A. PENROD, a cltizen of the Unlted States residlng at State of Ohio, have invented certain new and useful Improvements in' Cookers and Boilers, of which the following is a specilication.

This invention relates to domestic heaters'and has special reference to that class of My invention contemplates the provision of means whereby a supply of hot water for domestic purposes may be quickly obtained and by the same means the cooking of food accomplished by. the utilization of heat given off by the hot water. To this end the invention consists in certain novel features which are illustrated in the accompanying drawings and will behereinafter first fully described and then more. particularly pointed out in the appended claims.

In the drawings- Figure 1 is a perspective view of an apparatus embodying my improvements;

Fig. 2 is a horizontal section on'the line 22 of Fig. 1; i i

Fig. 3 is an enlarged vertical section of the cooker.

In carrying out my invention, I employ a boiler or heater consisting of a double "walled cylinder 1, the space 2 between the inner and outer walls of said cylinder being utilized as a water chamber. The top 3 and the bottom 4: of this cylinder are imperforate and the entire cylinder may be covered with asbestos in order to prevent waste of heat. The cylinder is preferably provided at its lower end with feet 5 whereby-it may be supported upon a shelf 6 secured to the wall. of a kitchen or other room, the said feet maintaining the cylinder'in spaced relation to the shelf so that aburner 7 for gaseous fuelinay be placed below the cylinder andpermit a flame to play directly upon the bottom thereof. Water is supplied to the annular chamber 2 in any preferred manner and in Fig. 1 I have shown pipes 8 and 9 which may extend. to the heating furnace in the] cellar of the building so that in cold weather when the furnace is in use the water in the compartment 2 may be heated directly from the furnace.

These pipes 8 and 9 are provided with cutoff valves 10 so as to control the circulation .of the water as will be readily understood. Dayton in the county of Montgomery and i A sight tube 11 is mounted upon the boiler near the top of the same so that the level of the water thereinmay be known at all times and a safetyvalve 12 is also provided at the [of the water should rise'to a danger point the excess steam thereby generated may escape. In the lower end of the cylinder, at

any convenient-point thereof, I provide a drain cook 13 through which the water may be dra'wn'off when it is desired to clean the device or through which a quantity of hot water may be drawn for various domestic purposes. This drain cock may, of course,

be caused to discharge into and through a hose or. other connection so that the water so drawn off may be carried to any desired point of use.

I have also shown in Fig. 1 upper and lower pipes'ld and 15, respectively, which communicate with the annular chamber or compartment? and are provided with cut-off valves 16 so that the circulation th'erethrough may be controlled. These pipes 14 and 15 are connectedby couplings 17 with pipes 18 'connectedto and communicating with the interior of a boiler 19 which may rest upon an ordinary kitchen range, indicated at 20. This'boiler 19 may be of any desired detailed construction and 'will be provided with a removable cover so that water may be poured into the boiler through the top thereof when it is to be used. A pipe 21 may lead from this boiler to a bathroom and adraw off pipe22 may also lead from the boiler to permit hot water to be drawn for any domestic purpose.

The interior of the cylinder 1 is divided into a plurality of compartments by horizontal partitions-which are preferably removable and are supported upon lugs, ribs or flanges 23 formed. on the inner wall of the cylinder. Communicating with each of the spaces defined by these partitions is a door 24 which is preferably hollow, as shown in Figs. 2 and 3, and filled with some heat-resisting packing, indicated at 25. Each door is provided with a damper 26 so that when desired the heat of the respective compartment may be reduced and each door is also provided with a latch'27 of any preferred form so that it will be held against accidental opening. The partitions preferably con sist of semi-circular metal plates 28 and a layer 29 of asbestos or other heat-resisting material disposed upon the metal members. The asbestos layers are also semi-circular in form, this shape permitting the several members to be easily inserted through the doorwa and laced u )on the sn 3 oortin 111 s or t 1 b C ribs with their straightedges abutting so as to separate and define the several coinpartments and, by reference to thefull and dotted lines in Fig. 2, it will be noted that the asbestos layers are disposed at right anglestothe metal sheets so that the seam or yooint between the metal members will be ridged by the heat-resisting covering.

As indicated in Fig. 3, food to be cooked is placed in convenient cooking vessels and 11316 vessels containing the food then supported upon the partitions and the bottom of theboiler or heater, after which the doors 2% are tightly closed. If tliefurnace is in use,the hot waterwill circulate through the pipes S and '9 and the water within the compartment or annular chamber 2 will be normally at a high temperature so that no furtherattention will be needed to accomplish the desired cooking. If, l1OW6VG1,'tl16 furnace is not-in use and it is not desired to heat water in the-boiler 19, the burner 7 is brought into use and the water in the cylinder or boiler 1 is thereby raised in temperature sothat the inner wall of the cylinder will be heated and. will throw off heat into the several compartments of the boiler and thereby accomplish 1 the desired cooking.

After the water in the annular chamber has been brought to the boilingpoint'or to an otherwise sufficiently high temperature, the

:fiame at the burner 7 maybe extinguished vessel 19 for domestic use, it will not'be and the heat contained in the water will then finish the cooking. If-the kitchen range 20 is in use or it is desired to boil water in the necessary to utilize the burner 7 as by opening the cutoff valves 16 a circulation of water through the pipesl l, 15 and 18 will be set up and the water in the cylinder 1 will be thereby brought to the desiredtemperature. .Vhen the furnace is in use, the valves I6 are closed and the couplings 17 disconnected so that the boiler 19 and the pipes needed, the water in the cooker may be ralsed to a cookingtemperature very readily by the use of'the'burner 7 and, consequently,

a metal surface on its under side and a heatresisting layer on its upper side. I The steam generated in the space below the partition will bepermitted to play directly upon the metal partition members and will heat the same but the heat will not be permitted to escape from the upper side of the metal members, owing to the presence ofth'e heatresisting layer thereon. All the'heatvwithin any one compartment will, consequently,be held therein to perform its office of cooking and the door to any one compartment may be opened and the cooking in that compartment inspected without causing anyfchilling of any other compartment.

Having thus described the invention what is claimed as new is:

1. In an apparatus for the purpose set forth, adouble walled cylinder, spaced annular ledges around the inner wall of said cylinder, removable partitions consisting of a plurality of mating sheet metal. members for each of said ledges and adapted to rest thereupon and dividing the interior of the cylinder into a plurality of compartments,

heat resisting members having the same size and shape as said sheetmetal members and adapted to rest thereupon, encased entrance openings being provided in the inner and outer walls of said cylinder, doors for said openings, said doors having recesses filled with heat resisting material, and a damper on each of saiddoors, said sheetrmetal members and said heatresisting members being of a size topass through said'entrance open- 'ings.

2. In an apparatus for the purpose set forth, a hollow cylinder with closed ends, a similar cylinder forming a casing around .the first cylinder with a space for heating fluid between them, annular ledges within said first cylinder, partitionsmade in sec tions adapted to rest upon saldjledges and.

.rlividing the interior of said first cylinder
